Retirement tax questions

So i have a similiar situation and want to make sure im doing this correctly:

 

To enter the nondeductible contribution to the traditional IRA for 2023: - I did this part no issues.  My contributions were slightly different ($6,000 in 2022 and $6,500 in 2023)

 

To enter the 1099-R conversion:  - My issue with this portion is my 1099-R mentions $12,500.  I know i need to fill out a form 8606 for 2022 as I dont believe that was filed in 2022.  Even though my 1099-R mentions $12,500 do I enter that into the box 1 and 2A?  Then in the step of "What did you do with the money", the amount converted to Roth IRA should be $12,500 again?  I wasn't sure in these steps if I needed to change to $6500 instead?  Thanks
